SYNOPOSIS will develop an active, long-wave mid-infrared (LWIR) imaging system capable of catering for a wide range of applications including the detection of explosives, oil and gas prospecting and medical diagnostics. To date, active imaging systems operate mostly in the short-wave mid-infrared spectral region. Moving the technology to longer wavelength will enable access to the so-called molecular fingerprint region where the interaction with light and molecules is significantly stronger, therefore enabling higher sensitivity and specificity. The limiting factor in the context of LWIR active imaging technology has so far been the availability of practical LWIR light sources. SYNOPOSIS will address this issue by advancing the continuous-wave, intracavity-pumped, optical parametric oscillator into the LWIR by employing novel nonlinear materials such as orientation-patterned gallium arsenide and zinc germanium diphosphide.

SYNOPOSIS将开发一种主动长波中红外（LWIR）成像系统，能够满足广泛的应用，包括爆炸物检测，石油和天然气勘探以及医疗诊断。到目前为止，主动成像系统主要在短波中红外光谱区工作。将该技术移动到更长的波长将能够进入所谓的分子指纹区域，在该区域中，与光和分子的相互作用明显更强，因此能够实现更高的灵敏度和特异性。在LWIR主动成像技术的背景下的限制因素到目前为止是实际LWIR光源的可用性。SYNOPOSIS将通过采用新型非线性材料（如取向图案化砷化镓和锌锗二磷化物）将连续波、腔内泵浦光参量振荡器推进到长波红外中来解决这个问题。
